Title:     Towards Quantitative Ab Initio Nuclear Structure

Abstract: Modern ab initio calculations of light and medium mass nuclei have reached a
point of unprecedented precision by combining low momentum interactions from
chiral effective field theory softened using renormalization group techniques.
However, thorough descriptions of uncertainty in such calculations is lacking,
both with respect to the many-body method employed and with respect to the
systematics underlying Hamiltonians.  This is exacerbated by many chiral
interactions failing to correctly describe medium mass nuclei, often over
binding while failing to correctly predict nuclear densities.  I will present
recent progress in quantifying errors in nuclear Hamiltonians as well as an
alternative approach to constraining chiral Hamiltonians such that predictive
calculations of light and medium mass nuclei are within reach.  I will also
present recent developments on understanding certain forms of error that enter
into many calculations of light nuclei.
